The t-con board usually fails on this model (Vizio E601i-A3 and e701i-A3) resulting in sound but no picture. Watch how I repair the t-con board with a $.54 cent transistor. The problem is noticeable when it seems like the tv is not turning on. You may hear sound but nothing is showing up on the screen.
Specs on the transistor replaced: MOSFET 60V 2.3A 1.66W 156mohm @ 10V

I installed a 15,600W power plant on my roof by myself. Check out the Video --> ruclips.net/video/ToxFObjnlF0/видео.html
Last week i bought and repaired a 42" Smart TV for $5. Is the first time in my entire life i'm having a decent tv
That is so amazing to hear! Thank you for sharing. Keep it up!
I repaired TVs for 22 years, starting with sets that still had tubes, later transister and finally IC chips. The new technology works great and has excellent features, but is too small for this old guy. It's a young man's technology these days. Bravo to you working with such tiny components.
Thanks! Working with a microscope makes it very doable. In order to record this video I couldn’t use my microscope and instead had to watch through the tiny screen camera which is partly why I had trouble holding the transistor steady. I just upgraded to a trinocular one so hopefully videos like these will be easier to record.
The good old days. Technicians back then used to do things like design and build their own Pay TV Decoders. My version, cost about $5. It did not require a power supply of its own, since It pulled only 15 mA, and thus you could just install it inside a TV converter and then tap the power from the TV converters 12 VDC line instead. The decoder PCB was 4.50" x 1.20". To install, you just had to cut the baseband video wire, the wire that leads from the demodulator to the modulator, and hook these wires up to the decoder PCB's input and output. Anyhow, it decoded the baseband video signal line by line, rather than use the complex frame by frame PLL method. Later on I tried to sell the design to a cable company. But they said that my design was too good. Meaning that it was far to easy for it to be copied, due to it having so few components, components that were also readily available to just about anyone.
Yeah i remember i was kid and a family friend come to us to fix our black and white tv....watching for hours searching the fault and the smell of the dust and hot tin i will have in my memory for ever.
Well I was wondering if you could help me with a problem I have a 55 in LG TV that I bought off someone and it had a picture perfect picture on the internet part you know show settings and all that but when I brought it home to hook it to my internet it kept saying put in passcode I put in Pasco says it again so I tried to hook a DVD player up to it and the screen turn white and fuzzy it has sound but you know it's white and fuzzy picture but when I unplugged the DVD player it just has sound and I don't know what it could be it doesn't have pictures you know of people or anything on it like it should have but it's perfect when you go to settings it's like nothing's wrong with it on settings
Paul, I come from the same background. When I started, my very 1st TV that I repaired (yes I still remember it) was a 1955 RCA Color roundie) LOL
'Same as you, tube sets, hybrids, transistor, chips and modular.
Parts are in fact so much smaller now. I actually stayed away from SMD stuff because of concerns of being able to work with such small components.
But then, I just said to myself... SELF, get off your duff and just do it! LOL
So I bought all the toys... I MEAN... TOOLS (cough)... electronic microscope, superman mag headset, SMD station and just recently, a vacuum solder sucker gun and an SMD oven... well... just a toaster oven that I modified using Arduino to use as an SMD baker. LOL
Now, I can say that I just love SMD work, even more than old-school, through board.
That being said, there are some boards that I have that have the SMALLEST PARTS I have ever seen. LOL Literally, you have to hold your breath around them (if not soldered on) because they will blow away.
But yeah, love it now. The electronic microscope was the best thing that I ever bought. Mind you, I don't use its own little display. Rather, I bought a nice 24" screen with HDMI input and it's just amazing.
This reminds of an old joke about a repairman who was called in to fix a household appliance.
He said "It's a bad screw, it'll be $100 to replace"
The owner was in shock, $100 for a screw???
Repairman explained "well, it's $1 for the screw and $99 for knowing which screw to replace!!!"
It's $0.54 for the component, $15 for shipping, $150 for hot air rework station, $75 for solder station...
lol

Exactly !!!!!!!!!!!!
Great clip! I was a TV repairman (old analog TV). Your video is really good, especially for techs, but I doubt an average person could do such repair (mostly due to the lack of tools and patience).
Thanks!
I recently fixed my 60" tv by replacing it with an 92" one

Hahaha
Super valuable video for a common fix on the TCON board for these Vizio models. I can't thank you enough; Vizio is all my family uses. Thanks for the tool descriptions in the notes above as well, also valuable info. These are the fixes that never make it to any manual, and it's so cool you took the time to explain it.
I did the same thing with my 3k, 10 yr flat screen by replacing four capacitors for $1 plus $4 in S&H 2 yrs ago. It was the first time my adult son got the chance to watch what his mother use to do for a living when he was a toddler. It impressed the hell out of him, lol !
thats pretty cool.
If you don't have the tools you can also use a cheap soldering iron of around $25.
To remove the broken component, heat each solder joint separately and use a sharp knife to bend up the pin while the solder is heated, so it's not touching the solder anymore.
To solder on the new component, put the new component in-between some tweezers and lower the side with the single pin just a little, so this side touches the solder joint first.
Heat the solder while lowering the component in place. When the side with the single pin is soldered, the pins on the other side should slightly touch their solder-pads underneath,
then complete soldering by alternating between both left over solder joints. If you notice you are bending the pin on the other side a little to much, just reheat this side quickly to release the stress on this pin.
or you can use a lot of solder, just make a big glob that will get cold slow and take the part out with tweezers. Clean the pads with a wick, place component, solder 1 leg while holding the part and then solder the other 2. Much easier and cleaner.
You're the man! I have a 60" TV in my basement right now waiting for me to replace some capacitors!
Keep us posted how it goes!
Hmm...you too can fix a flat screen TV for $0.54...if it happens to need this particular transistor, never mind how we diagnosed the failure, and you have a hot air rework station. I once saved a stereo receiver with a $1 capacitor, too, but that was the only lucky shot I’ve had. The other jobs took a lot of troubleshooting and had more involved failures.
he coulda fixed it with just a soldering iron. but I understand what you mean. my mate fixed a four-year-old 60inch telly using NO parts. (just squeezed up a screen connector). but I think it's worth having a look if you have a few tools and basic skills - if you can't fix it, there's nothing lost. if you can it's a result
The amazing thing is how little is actually wrong with these tv's. This is a wonderful channel to clarify exactly how you fixed these models. I can't wait to take another look into my bad tv because it could well be some very inexpensive part(s). Very helpful! I enjoy fixing stuff too.
Are you sick Mr Rossman? You sound funny today and you're fixing TV's instead of MacBooks
joblessalex Louis doesn’t solder that bad
I just picked up a vizio 47" tv for free the seller described it as the backlight went out on the right side, so I brought it home (this is my 5th tv I've fixed from my crona quarantine away from school for the past months thanks to you! Btw lol)well I decided to plug it in to see if they where correct and all the sudden I hear it squeal and smoke comes out of it!!😂 well I take it apart and look at the backlight inverter on both sides sure enough the right side was burnt from the capasitors smoke and the left side capasitors where bulging so I ordered 5 new ones I only need 4 but why not have extra lol for $6.99 and now it's running perfectly strong and has been for a week. Sorry for the long read but I figured I'd put my story if it might inspire someone to get after there broken tv and fix them.
That’s so great to hear!
this is your bread and butter, how reg joe gonna know that transistor is the culprit?
How didnt you see the moment where he is measuring that very component.... It isnt that far fetched that understanding its inner workings it is much easier to go and look for failed components. Because they are most commen to fail just hard to find if you dunno what is controling what. Just grab yourself some broken tv a multimeter and go have some great fun. But remember to stay away from the high voltage area...,if you dont you find out really fast why. Good luck! Stay safe!
Most issues like this can be quickly checked with under $150 in tools, and a quick google search of " common problems". I have done this numerous times for all sorts of various electronics and it has saved me not only thousands of dollars in repairs, but hundreds of hours of manual troubleshooting.
Newer TVs are easy to fix now even if you do not want to change a transistor you can buy the boards cheaper than buying a new TV and just replace the board. I have fixed a few TVs over the years. The old tube TVs were easy you just pulled the tube out, took it to Radio Shack and got a new tube and replaced it lol.
Exactly. Swapping out boards is pretty easy and you only really need a screwdriver.
No doubt the TV repair chains lobbied for tv's with no tubes so you'd have to pay a technician an outrageous fee to replace a 5 dollar circuit board. I remember fixing my own TV many years ago by testing for those burned out tubes. Cars were owner repairable also.
@@kenjsr1 Valve TV's?? you still in the 60's? LoL. Music was good, TV's were rubbish.
Nice job on the video. Very clear photography. I really thought this would be a video about a bad capacitor. I have a ~15 year old LG 27" 1920x1200 monitor that I fixed many years ago. I learned what was wrong by searching the Internet forums. My search taught me about "capacitor plague." Ballooned cheap knockoff capacitors that caused many electronics to prematurely fail. I replaced the bad capacitor and my LG is still going strong today. I agree with you. The Internet is a wonderful resource for DIY'ers.
Thank you! Great to hear you fixed your monitor. Yes, so many tvs and monitors were hit by that "plague".
Most solder has flux in it and also I would never use hot air station its risky and for repairing one thing its pointless.
Just use a soldering Iron it's cheap and it works well and its safe if you use it right.
My thoughts exactly.. For a 3 pin component it's useless. Just pump the solder from the board, put the transistor on place, and solder it with a simple iron..
@@freeeflyer Did you mean: suck the solder from the board...? I have a solder sucker...never heard about solder pumps... :)
@@bror8228 If you need to desolder lots of connections, you can buy a solder station fitted with a vacuum pump and nozzle.
Who needs a solder suction pump for a job like this? Just use solder wick. Should have cleaned off all that excess solder so the new part leads are in contact with PCB with minimum solder in between. That huge pile of solder this guy used is more likely to crack than if it were minimal.
Also soldering one leg to tack it in place with an iron is easy and then you only have to touch the other pads after you have cleaned and added new solder to the pads.
Great how-to video. You explained it well enough so that I feel confident enough that I could do the repair on my own TV if need be. The link to Ali-express for the soldering iron and hot air combo was a nice touch because although it is cheap equipment, it would probably last long enough to make a few repairs and save me the cost of replacing the entire TV.
Thanks! I’ve been buying a lot more from AliExpress this past year and I’ve been happy so far.
Thank you for this great info! I replaced the culprit mosfet with a random mosfet I desoldered from a random board. The tv turned on for a few minutes before blacking out again. This confirmed your suggestion that the mosfet is burnt. I can now go look for the correct spec mosfet to repair my tv. Tv is a SONY KDL-70R550. It’s an old dog but if it costs 50cents and a bit of sweat to repair I’m happy to continue using it.
That model uses the same tcon? Keep me posted.
FrugalRepair it’s using the 5348 board but the layout is identical. I’ll keep you updated with further developments
I couldn’t find the mosfet of the exact spec that you specified so I tried my luck with a SI5328DS mosfet rated for 100v. It works and the tv is back working
Fix the car
If you prepare the lands as you did, plenty of flux and use a soldering iron to make each land. DON'T use hot air to place the new component in!
Right. This was almost like a "how not to" video for SMT soldering. I was cringing the whole time.
Any problem with hot Air? I mean some do solder set with hot air right any reason to avoid it?
Jon C. - unnecessary for this particular component with three leads. If it was a chip with lots of leads, then a soldering iron won’t be the tool to use.
As an EE, I salute you for the knowledge of an appliance, plus the incredibly small working parameters. I've never thought of using a heat gun in lieu of an iron, however small.
Thanks! I studied computer engineering, all those EE classes have definitely helped me understand what components are and what they do.
@@FrugalRepair so when the screen is black it's most likely the T.comm board and not the main board,I'm asking for a friend. .....

Congrats fixing your big screen TV it's nice, a big thumbs up 👍and shared.
Wow, I'm honored! You made my day. Love your channel. Thank you!
Screen is tore half an inch not cracked can we fix it
You mean that there is a scratch in the screen? You probably can't fix it but you can minimize the damage a little bit. The part you touch on the lcd panel is the front polarizing film. That is glued on to the lcd with clear adhesive. Its been a while but depending on what kind of scratch and how deep, I've used a pencil eraser or a black permanent marker to mask some of the imperfections.
But now he end up with Vizio...... Not sure that a good thing...
please send me the T-con number for JVC MODEL LT- 55N875 smart tv
there was a great TV repair shop down the road for many years. The guys that worked there were honest & fair, once not even charging me at all for a overheated receiver. sadly with the cheaper almost disposable TV's from overseas now many people just toss them out rather than try to have them repaired. This being the reason the TV repair shop had to close. just wasn't enough business.
“You need really steady hands for this.”
Damn. Count me out. 😀
Just found your channel, the issue with my vizio is all the input ports stopped working so we cant plug anything into it. Lots of great stuff on your channel, I also try to help people save money by fixing thigs. Thanks for sharing.
It’s the skill of finding that failed part that makes the repair bill, plus your soldering station, access to schematics, multimeter, etc.
schematics.... many of electronicians don't use schematics for fixing boards, we uses them 20-30 years ago, now theire not avaiable for the most of them. So, we tests, we try, and maybe we fix...
And more modern boards with macro smd's no chance repair for diy .....
@@leso204 1206 SMD models (and biggers) are not so hard to tests and replaces, but for the tiniests ones (402, 201 and smaller), i'm ok with you, what a pain to try to test and even more to replace :/
Less than $1 if you have tools ready
And schematicvs of the module, probably not less than $20.
No chance he weould get the right transistor type from that marking alone...
@@BB-ce3bj making he looked in an online forum where someone had the same problem
Wilcon Barro Yes. As with most repair jobs of any type, you will need tools. They probably cost a lot less than the repair shop or the price of a new TV though.
Multi meter is like 20 bucks at Walmart.
Soldering iron 10-15
Flux 3-4 bucks or free with soldering iron
"Fume extraction" get a house fan
Hot air shit not necessary and most likely you'll damage something else if you don't know what your doing not worth the risk
Les then 40 and you'll have useful tools in the future just in case.
I had a coworker from work give me a free broken Vizio M series TV that has this exact issue! I bought a TCON board for the TV but the model number of the one I got on ebay was slightly off, and as a result it is physically smaller with different ribbon cables. I might take a closer look at it, though I might have cracked the LCD in the handling of the unit.
Well done! This is a great help for DIYers like me.
Thanks!
Way too much flux. But good job fixing it!
The bigger the glob, the better the job - Louis Rossman - 2017
You didn’t clean the flux residue off. At least wipe the area with a flux cleaner pen as a final step.
Enough FLUX to do a plumbing repair and far too much SOLD ER.
OMG you a tech genius, u saved a tv that had the exact problem but different model my tv was model 43R6E3 and it worked! Thank you for the pointer as soon as I saw the video I knew we had the same problem.
Congrats on the repair!
Question is how did you know out of all those components that one transistor was bad? Did you test all the components on the display board or something?
He literally explained that this was just a suspicion before testing. Many repairmen work like this. You don't have the time to check everything so you just move down a list of parts that have a high likelihood of failing. If this TV is known for a particular part failing then why even bother with the other parts?
He watched another RUclips video on this common issue..
Well but if you don’t know where to look, its an awfull amount of transistors and capacitors to test.
Have you heard the term "reflow" in repair and wondered what that means? Watch as I explain and use heat to get the HDMI ports working again on a TV in my latest video: ruclips.net/video/CLLADvGJiSU/видео.html
It was painful to watch you trying to work with those tweezers lol
I would be the same way. That is a small transistor. I get the shakes when soldering small stuff also. :(
yeah i cant bear to watch him using those tweezer
Same feeling
Oh the perfect people can't stand it. Must be nice to be so flawless. Douchebags.
@@Darmidion, No one is claiming perfection. It's simply about avoiding damage to the board. Rocking a component like that before the solder reaches it's melting point, can rip the pad right off the board.
Definitely not a fun situation to deal with.
Seems somehow you forgot the word "Repair" from your title.
It’s in the thumbnail
But not in the title.

No longer apprehensive about purchasing a Vizio again. Thanks.
You probably can't know ahead of time who makes the TV until you open it up. Vizio doesn't make the TV's actually. Usually the manufacturer is LG, AU Optronics, or even FoxConn (who makes iphones). I've even seen the same exact vizio model made by different manufacturers.
Can you help me fix my flux capacitor I’m stuck in 2018 need to get back to 2055 😁
Haha! One of the best comments on this video. =)
No wonder your flux capacitor failed. It says "made in Japan".

Just add new flux.

I enjoyed watching this video, especially the soldering works for the new transistor. It s like watching man landing on the moon.
Than you for the encouragement! I think I did a better job explaining the soldering process on the 65” 4K TV video. Did you get a chance to check that one out?
Oh,, your tv is dreaming inside a dream..😱😱
I did tv and radio servicing C&G 224 many many moons ago, it was all analogue back then everything was solid state..... very easy to fix compared to these smd's you deal with, respect to you.
Thanks! The biggest hurdle I find is lack of schematics and board views. It takes a lot longer if you have to reverse engineer stuff to figure out the problem.
Good job, since it costs you .54 I can pay you 1.08 plus shipping if you send it to me. That's a whopping 100% margin.

Last December, one of the sales guys where I work was tossing a Hisense 50H7709 4K 50" LCD HDTV. It was still under warranty and after a tech tried troubleshooting it, he authorized it being replaced, so he got a brand-new replacement. I asked him if I could take it instead of tossing it and he said yes. It would power up, show the Hisense logo, then shut off again. I looked at the power supply board...BLOWN CAPS! Easy fix! How the tech didn't see it I'll never know. Anyway, ordered 4 caps (2 for the fix, 2 just in case), replaced the blown caps, powered up and worked beautifully! I gave it to my daughter as a Christmas gift. The shipping on the caps cost more than the caps themselves. Just over $8 Canadian in total.
(I may have posted this before, but I can't remember. Please forgive me but I love to brag about this one.)
where can I buy those little chips without having to buy 1000 of them?
Search online with the specs I gave. Aliexpress has them or equivalent mosfets in lower quantities. arrow.com and possibly ebay too. Of course you can buy from other chip sellers too.
Superb fix - So many flat screens being thrown away nowadays simply because of faults/issues like these which can ultimately be repaired with knowledge.
Yes, it happens all the time. Usually it is a fairly simple fix. In this particular model you don't even need to go to the component level like I did. You can easily buy a new tcon on ebay for like $20 and with a screwdriver replace it.
@@FrugalRepair I worry about such purchases what if someone sells a bad board?
@@dannygjk It's usually not a problem, just send it back for a refund. Even ebay sellers who have a "no return" policy will almost always (since they care about their rating) will take things back.

Dude have you lost your mind
Typical in any sort of repairs, the part is cheap, but the knowledge and know how, takes years.
And it appears, very steady hands, and the tools to do the job.
Nicely done.
While I was younger, and better eyesight, I may have been tempted to try a repair.
These day, I’d throw it out and buy a new set. Or if I were lucky, find someone with your skills and pay for your talent.
Thanks for your comment. Actually with the internet diagnosing a board that has a common failure doesn’t have to take very long. It is because other people find the faults and share the info online. Those issues that no one has come across before (or posted about) are ones that can take a bunch of time to track down the culprit(s).
Thats amazing, my brother did this to his TV and got it to work just fine, thank you for the video and pointing people in the right Direction!
That’s great to hear!
Wish I could like twice.

Well considering I work in a electronic development group at a research lab, I beg to differ.


REPLY
@@maddog187killa you might know how to clean the floors or write some user manuals but if you think you don't need flux to get a clean solder joint you definitely have nfi how to solder.
The bigger the glob, the better the job !
@Damnit Bobby it definitely matters, if not cleaned up properly.
You can also get a new T-CON board they are pretty cheap,but I highly suggest looking at your Mainboard first and assure all of the cable bands and cord are tight clean and secure. Definitely try the free options first.
I just replace the whole boards. Sometimes a failure just leads to more failures.
Good job. Give us some diagnostics, so we can "learn" error tracing of broken components. Keep up your great work! :)
Thanks! I'll bear that in mind for future videos.
Great video , but majority of people don’t even know what is what when it comes to electrical goods, the culture of throwing out needs to be changed by having the repair specialist more accessible
"Only $0.54!!"
> using $500 rework station.
That transistor could have easily been replaced with a 10$ soldering iron, given that it wasn't connected to a large plane with high thermal mass.
coulda done it with just the soldering iron...…….
...and $50,000 for the college education to learn HOW to find the problem component(s).
The part could have been replaced, and probably far more accurately, by a $10 pencil iron.
@@alphabeets Of course, because you definitely need an expensive college course to learn things nowadays when the internet is so widespread.
You do not need a hot air station. Just use some chip quick and tin all the pads and slide off the old transistor. Then make sure to wick the rest of it off then solder the new one. Both methods work.
It's ONLY "cheap" when you've completely know exactly what you're doing and knowing exactly where and how you could have diagnosed this exact problem.
For most of us, we'd have to pay someone to tell us exactly what's wrong with a tv like this. Replacing components are way easier than fixing this exact problem. Great Tech this man is though and enjoyed watching this,
Thanks for sharing, in this day and time we need to change our way of thinking. With the pandemic that has arrived there's going to be a point where there will be issues of being able to afford the luxury items that we have been accustomed to buying. We are definitely going to need to repair what we once threw away, or the option will be to do without. If one thinks that the Great Depression was only a thing of the past, you're in for a surprise. You've earned a new subscriber.
Thanks! Great perspective.
I'm so grateful I came across this video this morning. Recently got a 75' M3D650SV , #1 home theater of that year $4,500. Screen is beautiful a guy was going to throw it out so I got it for free he just said the sound went one day recently so that's why I got it I said well I'm not going to let that go to the landfill when I can just add a sound bar or something at the very least but I'm not a Mr Fix-It man or even close probably just the opposite so I'm looking for any kind of advice or your opinion please... Thank you
Sounds like worst case it would need a new main board. You can look up what a used one on ebay is. You may want to test all of the various tv inputs to see if any others have sound, to see maybe if it's an HDMI related issue.
Yeah, 54 cents part but $8 shipping and handling. ;)
Not really, you can a lot of stuff shipped for free from aliexpress.
Do you still get that rush/instant gratification feeling when powering on the flatscreen, after doing the fix, and it instantly works? I do and that's the reward for a job well done.
Totally!
I have an 11 year old 42" Panasonic plasma tv that still works since I first turned it on in 2009… I'll just toss it to the recycling yard when it finally dies on me. It's a power hog compared to today's TVs with the same screen size. I repair everything I can repair though… from clothes washer & dryer, amps to my '06 CRV and anything in-between… saves me tons of money.
Awesome! Great to hear you fix all of those things. If that Panasonic dies, chances are it might just need a capacitor or a voltage regulator replaced.
@@FrugalRepair thanks for the tip… I'll keep that in mind, perhaps I'll have a change of heart. That plasma tv is actually THX certified and cost $1,000 back in the days
Its a great video but how would anyone ever know a specific transistor shouldn't chirp? I wonder how much the replacement board is.
Wow 54 cents?
Minus the $200 hot air station
The $60 soldering iron
The $10 flux
You dont just wake up one day with all the tools and knowledge of a skilled trade...!? Wtf We should complain to the government about this discrimination against ignorence.
Soldering irons are cheap though
store.rossmanngroup.com/index.php/quick-861dw.html! Less than $300
And still cheaper than buying a new 60", plus those tools can be used over and over to save even more money.
But most folks go for the convenience of replacing today's flood of crap quality products.
But manufacturers know this about human nature, hence the intentional crap quality.
Convenience saves time, but costs you far more than you realise over the long term.
And the electricity
I really like your channel personally .... You provide very good content...
Fake that tv was a paid actor
Yes because he likes to make people to subscribe his Channel
😂😂😂😂
Horrible soldering job there.
3:42 protip , blow hot air directly to component from the top, not from the angle. you can make little circle moves on bigger components to not damage pcb.
Thanks, I just got some bent nozzles to help with that. Also, to film this video I replaced my microscope with my camera and had even less working distance.
I love doing such things. Save money and also learn technology to fix the broken things.
Great to hear!
that reflow was kinda cringy....
nikushim666 but he got there in the end. Can’t knock a bloke for giving it a go and showing the world at the same time. I don’t disagree though...I’ve been watching too much rossman.
@@Clynikal Oh i have been doing it for years using a old aoyue knockoff rework station. But those solder joints are cringy. He could of just cleaned the pads and used solder paste and did a far better job. Even hand soldering would of been better.
I like you ...... You really shared good info. ... I was not able to repair the tv ...
But after your knowledge it workssss
Thanks!
when you remove transistors like that just use clippers and cut it off and than solder the rest away is much easier. And you should not put any of solder on pins, just transistor and solder iron and iron one pin than it is easy.
So happy I found this. I have a Vizio 60" I bought from Best Buy 4 years ago. The backlight is very uneven, easily seen when the tv displays a light background, i.e. white background on last week with John Oliver. Some areas very bright and some areas very dark. I heard Vizio will not fix this. Can this be fixed?
It can be fixed though it may be quite involved. You can also try mitigating the problem. I explain more in my top tips pdf that is free on my website. Link is in video description in case you’re interested
Can you help me fix my remote it don’t seem to mute my wife. 😂
You seriously throw TVs and electronics into the landfill in America 🤯🤦🏻♂️
Which country doesn't that happen in? It is painful to watch the trash (rubbish) truck getting loaded up on Monday mornings around here when bulk items are picked up.
FrugalRepair well in Germany, where I live, and I’d say in the other European countries as well, all electronics are disposed in recycling facilities. how, where and who is recycling the items is a different story. but all the valuable materials are reused and don’t end up in a landfill as a whole...
I don't , the guy in the big garbage truck come and takes it.
There are e-cycling programs in my area which properly recycle scrapped electronics. I see a lot of old CRT televisions and monitors being scrapped it is a good thing because the CRT's have a lot of toxic material in them.
I fix many touch screen 47" LG Using bypass method in different spareparts and it works but surely doesn't sure 100 % guarantee, beacause sometimes the value of the component is erase or none...Congrats to you bro!
Nice! I have 4 dead TV's, can I send them to you? I will give you $5
🤣🤣🤣🤣
Modern tvs have incredibly well made video processing boards and a power supply made out of paper and glue.
I mean, that's literally what you do to fix them. Add paper, in this case soldering material, and glue, which this is literally a kind of glue.
Cheap, effective, and sticky.
Seriously man, you should fix the title of the video to include the word "fix."
so .59 cents plus the cost of diagnostic hardware tools and a hot air soldering station. So ya, you're in the hole.
I love finding a broken tv that just has an issue with the power board. Usually it's just a quick soldering job with new capacitors or ordering a new board.
That’s the tv I threw out?!? Give it back
Is it possible to just order a new T-con board? Assuming one is not versed in the art of soldering...
Yes, that is a good option just to replace the tcon board.
I'm impressed. I just subscribed to your channel but hoping to not need your knowledge any time soon!
Thanks! Hopefully nothing breaks and it stays as education and entertainment.
If a transistor fails, something else failed to kill it, or it will fail again due to incorrect tolerances. Typically they fail shorted for only a brief time, then they release the smoke and fail open. Most likely this transistor feeds a circuit with capacitors that bleed down on every cycle and it’s not rated for the power on inrush it experiences or simply is rated too low for its working current. I would inspect the circuit and add a current limiting resistor to dampen capacitor inrush current or upgrade the wattage of the transistor to lessen the likelihood of future failures.
That was a very good and professional repair
You help really help me to fix horizontal lines
